Aircraft Climbs

After take off my aircraft takes on a pitch up attitude until eventually it stalls. Adjusting trim makes no difference as trim constantly goes back. This happens even if the autopilot is set and on all aircraft, any ideas?

Thanks Fozzer, I will give it a try.
-TRIM FOR TAKEOFF
-TRIM FOR TAKEOFF
Shouldn't that be "neutral trim"?
